The game is now split into the launcher and the data packs. 

The launcher can be found in downloads:

Once you downloaded it, install the APK. You can install it on top of your previous Android install of AHITR. Launch it, and grant the permission to manage files to it.

You should be greeted by this screen:

If launcher quits by itself, make sure it has file management permissions. 

Then you'll need to download the .rpa pack. You can find the packs in downloads as well.

Once downloaded, you will need to move the pack to Internal Documents\ahitr_storage\game\ folder. 

You can do it with basically any file manager, even Files by Google should do. 

After the pack is placed, relaunch the launcher. Now it should load the full game.

You can also see all your saves in the ahitr_storage folder now. If you want to, you can move your Android saves to PC, or place your PC saves there. They should be available after you relaunch the game.

Enjoy!
